Circular, main, and lateral depression channels passively drain and direct liquid efluent into one of three opening arranged linearly along the main central channel. The dual migration ramps begin their gradual 30˚ assent at the central depression, allowing the grubs to auto-separate from the active pile. Upwardly migrating larvae leave the unit automatically via the shared top exit portal.
BASE STAND
The 31" square, stainless steel base stand has been designed to amply support the weight of a full ProtaPod™. It SS201 coating helps resist the elements over the years, ensuring long life. By elevating the unit off the ground, the filters and the liquid collection jars are easily accessible with needing to tip or move the pod. Each stand weighs approximately 11.5 lbs (5.2 kg). Rubber stoppers on each leg protect ground surfaces.
TRIPLE FILTERS
To prevent anaerobic conditions from developing, all liquid is continually drained by one of three removable filters. Inside each filter is a cleanable, resuable media pad that allows liquid to flow while simultaneously preventing most large particulates from exiting the system. Since black soldier fly grubs are instinctively top feeders, minimal loss of juveniles occurs through the filters.
COLLECTION JARS
Three lightweight collection jars sucessfully contain all liquids generated by the pod. Without full capture and retention of all effluent, gravid females would inadvertently lay eggs in inappropriate locations, since the pod tea is a strong attractant. Jars are easily removed, emptied, and replaced without disturbing the associated filter or colony above.
